‘^Second stage . — Head only very sliu’litly depressed on top; rounded, green, not sliining; jaws 
reddish; a black stripe extends from the ocelli up the side of each lobe, running posteriorly, not 
attaining the vertex and diminishing in width upward; width, 1.1 nim. Body smooth, with 
minute dark setm; green; a faint stigmatal yellow line; all the feet except the anal ones are black. 
Third stage . — Head flattened before, clypeus small, depressed; median suture deep, but the 
head not bilobed. Light green, not shining; a mottled brown bund from jaw on each side, not 
attaining the vertex, but narrowing ui)ward, black at its extremities; ocelli black, jaws green, 
tipped with brown ; width, l.S mm. Body smooth, the. setm minute, green, with four narrow yellow 
bands on each side the lower substigmatal and bordered above narrowly with red-brown. 
Thoracic feet blackish; abdominal ones black-tipped. The anal feet are not elevated, and are 
used in walking, but they are small, and joint 13 is tapering. 
'^Fourth stage . — Head shaped as before, always large for the body, held out nearly flat, recalling 
the i)osition of the head in Gluphisia. The line on the side is red-brown, bordered on both sides 
with yellow, and is continuous with the stigmatal line of the body in the normal position. It does 
not attain the vertex of the head, terminating in a black point at each end. Jaws yellow, with 
two small reddish lines. Later the sides of the clypeus are defined by a pale j^ellow line and there 
are two little yellow streaks at the vertex of each lobe continuing tlie lines on the body. \Yidth, 
2.0 mm. Body green, including the feet, wliich are only faintly tingeil with blackish, the thoracic 
ones most strongly .so. Slender, tajiering posteriorly, the last segment small, though the feet are 
used in walking and are not elevated in the normal position of rest. No cervical shield nor anal 
l)Iate distinguishable. There is a broad, double, dorsal, and single, waved, subdorsal, whitish line; 
a lateral row of j^ellowish dots, obsoletely connected into a wave<l line, and a distinct, straight, 
narrow, stigmatal, yellow line, bordered above with red-brown. Spiracle on joint 2 large, black- 
ringed, the others reddish. The larva eats away the substance of the leaf from a midrib or vein 
which it leaves and rests upon with the head generally turned toward the base of the leaf. 
Fifth stage . — Head full, rounded, a little higher than wide, flattened in front, the sutures not 
deep; smooth, shining green, under the lens minutely granular; jaws yellow, with a broad central 
reddish band, and tipped with black; anteniue white, the last joint reddish; a red-brown at joint 
3 iiosteriorly; the second widens rapidly, reaching below the band over the ocelli, running 
posteriorly to about the middle of the side of the head, in line with the stigmatal band of the 
body, bordered, on both sides narrowly with yellow; ocelli black; labrum pale, a whitish line on 
each side of the clypeal sutures, and a faint double mark at the vertex, continuing the double 
dorsal line of the body. Width, 1.2 min. Body cylindrical, smooth, tapering posteriorly; joint 
13 small, the last feet no larger than the others. Setie not distinguishable. Dorsum leaf-green, 
with a suffusion of white, a distinct white geminate dorsal line; a very faint, narrow, waved and 
broken siibdors^l one; a lateral row of yellowish dots, obsolete at the extremities, three on each 
segment, the central one higher than the others; a distinct yellow stigmatal line boixlered above 
narrowly and irregularly with red-brown. Spiracle on joint 2 large, white, black-ringed, the 
others whitish an<l brown ringed. Snbveiitral s])ace clear green, unspotted. Thoracic feet i^ale, 
testaceous, with a few black dots outwardly. 
‘‘The larva seems a close ally of Nadata, but differs in habit, for it rests on the edge of the 
leaf instead of the back, as Nadata does. In its normal i)osition the clear green of the subventral 
space joins nicely wdth the green of the leaf, and the distinct stigmatal line seems to represent an 
edge or rib of the leaf. 
“ Cocoon . — Found beneath the surface of the earth; composed of silk mixed with grains of dirt; 
elliptical, thin, complete; size, 25 by 12 mm. 
— Cylindrical, rounded at both ends, thickest through the fourth abdominal segment; 
anal end almost flat; no cremaster, but a low rounded prominence. Cases creased; abdomen, 
sparsely punctured; color dark mahogany brown, shining. Length, 21 mm.; width, 7 mm. 
“PooJ plant . — Oak (Quercus). 
“Larva; from Cbnton County, N. Y.” (Dyaij. 
Pupa . — Body full and plumx), but not very thick at the end; of the usual form and color; the 
end of the abdomen very much rounded and obtuse, with no rudiment of a cremaster, only a 
rounded knob. The segments slightly, not deeply or coarsely, punctured. Length, 18 mm.
